Abstract

PURPOSE: Copolyamide fibers that are composed of specific structures as recurring units and useful for industrial fibers as reinforcing materials for rubber products, ropes, filter cloths, a variety of covering cloths and others because of their high initial modulus, tensile strength, knot strength and heat resistance.
CONSTITUTION: Said copolyamide fibers are substantially composed of rccurring units of structures shown by formula I, II and III wherein the units of formula I and II is substantialy equimolar with the unit of formula III and the molar ratio of the unit of formula I to that of formula II is 10/90W50/50. A copolyamide with an inherent viscosity of over 2.0, preferably over 3.0 dl/g measured with 0.5g/dl solution in 95W98% sulfuric acid at 30°C is wet spun using conc, or fuming sulfuric acid as a solvent and water as a coagulant, forming fibers with initial modulus over 400g/d and tensile strength over 16g/d.
